▎ 摘　　要

NOVELTY - The material is prepared by dispersing graphite oxide in water. Nickel salt and cobalt salt are mixed according to mol ratio of 1: 2 and stirred in water to obtain graphene oxide dispersion liquid that is frozen and dried under nitrogen atmosphere of 200-400 degree Celsius for 1-5 hours to obtain two-dimensional coral-shaped nano cobalt acid nickel. USE - Nano cobalt acid nickel material. ADVANTAGE - The material has wide application range and better economic benefit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparation of a nano cobalt acid nickel material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a nano cobalt acid nickel material preparation method. '(Drawing includes non-English language text)'
